Scientists have successfully transformed guinea-pig heart-muscle cells into pacemaker cells, paving the way for a biological alternative to artificial pacemakers. Pacemaker cells generate electrical ...

The human heart rate is under the influence of various hormonal and neural control mechanisms. Normally, conduction of an electrical impulse through the heart begins at the sinoatrial (SA) node and ...

A healthy heart beats 60 to 100 beats per minute, but when that rate slows down, patients require a pacemaker. Experts say traditional versions are bulky and need two ...

The CResPace project is developing a new pacemaker that works in conjunction with small artificial neural networks to better adapt to the demands of the body—replicating a healthy heart When the heart ...

Researchers have created new artificial intelligence software that can identify cardiac rhythm devices in x-rays more accurately and quickly than current methods. Researchers have created new AI ...

Your heart’s job is to keep your pulse steady to pump blood throughout your body. Sometimes your heart rate is slower when you’re relaxing, and sometimes it’s faster when you’re exercising or stressed ...

Pacemakers and defibrillators of the future may generate an extra power boost from a surprising energy source: The heart itself. Using a microgenerator powered by heartbeats, a British team said on ...

An increasing number of reports suggest that cardiac arrhythmias are frequent clinical features of COVID-19. A New York-based team of researchers explored the impact of SARS-CoV-2 infection on the ...
